STREET-INDICATING DEVICE FOR TROLLEY SYSTEMS.

To all whom it may concern Be it known that I, IVILLIAM C. BIsnLL, acitizen of the United States, residing at lVardner, in the county ofShoshone and State of Idaho, have invented certain new and usefulImprovements in Street-Indicating Devices for Trolley Systems; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements in circuit closingapparatus for trolley mechanism, affording means whereby a circuit maybe closed at intervals for actuating mechanisms of different kinds.

The invention comprises various details of construction, combinationsand arrange ments of parts which will be hereinafter fully described andthen specifically defined in the appended claim.

I illustrate my invention in the accompanying drawings, in which Figurel is a side elevation of a trolley car showing the trolley line and armwith contact points adapted to cooperate with electrical connectionsupon the trolley arm to close the circuit. Fig. 2 is a detailperspective view of a portion of a trolley arm and line wire and contactpoints for closing a circuit. Fig. 3 is a sectional view on line 33 ofFig. 2.

Reference now being had to the details of the drawings by letter, Adesignates a trolley car, B the trolley line and C the trolley arm ofthe usual construction, having a trolley wheel D moving in contact withthe line wire.

While it will be understood that the present invention relatesparticularly to circuit Specification of Letters Patent.

closing devices, I have shown in Fig. 1 an outline of an indicator box Ewhich is adapted to be connected to the circuit wires S of the trolleywhereby, when the trolley wheel comes in contact with the fingers R,certain indicating mechanism not shown may be actuated.

Fixed to the trolley wire are the fangs or contact fingers R pivotallymounted upon projections B of the trolley line and are disposed in thepath of the wheel T which is rotatably mounted upon the split shell orcollar T of the trolley pole and insulated therefrom, said wheel Tforming a terminal adapted to contact with the depending fingers R.Circuit wires S electrically connect with the collar which in turn iselectrically connected with the wheel T and affords means whereby anelectric circuit is formed through the indicating device. By theprovision of the wheel T, it will be noted that, in the event of thetrolley wheel D jumping the trolley line, said wheel T will notinterfere with the trolley line in the event of its coming in contacttherewith.

"What I claim to be new is:

A circuit closing device for trolley apparatus comprising a line wire,members fastened to the line wire, depending fingers pivotally connectedto said members, a trolley pole, a wheel mounted thereon and adapted tocontact with said line wire, a split collar fastened to said pole, and awheel journaled upon said collar co-axially therewith and adapted tocontact with said depending fingers to close the electrical circuit.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
